Abstract根据星载遥感图像的相邻像元间具有平滑性、均一性等特点,提出了一种二维均值预测方法(Mean预测)。该方法以被预测图像的两个相邻像素作为预测基准,通过计算两点灰度值的平均值然后向下取整,得到预测值,Mean预测残差近似服从Laplace分布,方法可逆。实验仿真同JPEG-LS标准中的MED预测、CCSDS预测和Zig-Zag预测做了比较,统计结果表明,Mean预测法与其它方法相比,在相关系数、熵值、均值以及均方差的性能上均有一定程度的提高,计算量小且硬件实现简单,可用于星载遥感图像的实时无损压缩处理。
Other AbstractA two-dimensional mean prediction method is proposed,according to characteristics of space-borne remote-sensing images,such as smoothness and uniformity among the neighboring pixels.The predicting value is obtained by computing the mean of two neighboring pixels,and then be rounded to the nearest integer less than or equal to the mean.The differences of the mean prediction approximately belong to the Laplacian distribution,and this method is reversible.The result of the mean prediction method is compared wi...
